In the title compound, C(16)H(26)O(5)S, the oxathiol-ane ring adopts an envelope conformation, with the S atom 0.793 (3) Å out of the mean plane of the remaining four atoms. The cyclo-hexane ring of the menthol fragment adopts an almost ideal chair conformation, with all substituents in the equatorial positions. In the crystal, relatively strong, short and linear C-H⋯O hydrogen bonds link the m...

The mass spectra of ethyl and isopropyl propionate and butyrate show rearrangement ions RlCOOH+ and RlC(OH)2+ formed by reactions [a] and [b]: R,COOR2+ --t RiCOOH+ + (R2 H), RlCOOR2+ --t R I C ( O H ) ~ + (R2 213). The mass spectra of ethyl-d2 propionate and butyrate show that both [a] and [b] occur with essentially complete scrambling of the alkoxy hydrogens. For the isopropyl esters the mass ...

The title compound, C(19)H(31)O(2)P, features a distorted tetra-hedral P atom that bonds to the phenyl ring, isopropyl and 2-isopropyl-5-methyl-cyclo-hexyl groups, and is determined as having an R(p) configuration. A chair conformation is observed for the cyclo-hexyl ring. In the crystal, mol-ecules are linked into chains running along the a axis by weak inter-molecular C-H⋯O hodrogen bonds.

Isopropyl (IPLA), N-methyl-N-isopropyl (MIPLA), N-ethyl-N-isopropyl (EIPLA), and N,N-diisopropyl (DIPLA) lysergamides were evaluated for lysergic acid diethylamide (LSD)-like activity. In rats trained to discriminate 0.08 mg/kg LSD tartrate from saline, each of the subject compounds completely substituted, with an ED50 two to three times larger than that of LSD except for DIPLA, which had an ED...

Insulin-loaded microemulsions for transdermal delivery were developed using isopropyl myristate or oleic acid as the oil phase, Tween 80 as the surfactant, and isopropyl alcohol as the cosurfactant. The pseudoternary phase diagrams were constructed to determine the composition of microemulsions. The insulin permeation flux of microemulsions containing oleic acid as oil phase through excised mou...

Thymol (2-isopropyl-5-methylphenol), and carvacrol (5-isopropyl-2-methylphenol) are the main components of the essential oils of some Laminaceae,Verbenaceae and Ranunculaceae members such as oregano, thyme, savory, etc. The formation of thymol and carvacrol is thought to involve hydroxylation of γ-terpinene and p-cymene precursors. They are produced by the plant species as a chemical defe...

The title compound, (C(3)H(10)N)(2)[MoS(4)], was synthesized by passing a rapid stream of H(2)S into an aqueous isopropyl-amine solution of molybdic acid. The title compound is isotypic with the corresponding W analogue (C(3)H(10)N)(2)[WS(4)]; its structure consists of a slightly distorted tetra-hedral [MoS(4)](2-) dianion and two crystallographically independent isopropyl-ammonium cations, wit...
